don't waste money on ate stuff. castrol srf or motul rbf 600 or 660 is the way to go

Don't waste MORE money on rbf stuff. ATE Blue or ATE Gold is the way to go.

(see what I did there?)

They're all great stuff, ATE is my preference because it is cheaper and still holds up to repeated track days (zero boiling for me), so it suits my needs. If I was endurance racing or doing more than just HPDEs, then maybe I'd need to look into a stronger fluid like 660. But I'm not.
